TL;DR
This paper applies the Fayans energy density functional to deformed nuclei in the uranium region, predicting ground state properties and the two-neutron drip line, and compares results with Skyrme EDFs.
Contribution
It introduces the application of the Fayans functional to deformed nuclei in the uranium region and compares its predictions with other EDFs.
Findings
Fayans functional predicts ground state properties of Th, U, and Pu isotopes.
The two-neutron drip line is identified for several EDFs.
Comparison shows differences between Fayans and Skyrme EDF predictions.
Abstract
Fayans energy density functional (EDF) FaNDF^0 has been applied to the nuclei around uranium region. Ground state characteristics of the Th, U and Pu isotopic chains, up to the two-neutron drip line, are found and compared with predictions from several Skyrme EDFs. The two-neutron drip line is found for FaNDF^0, SLy4 and SkM^* EDFs for a set of elements with even proton number, from Pb up to Fm.
